Changing Your Computer's Settings

At some point, you'll probably need to change some of the settings on your computer. OS X Mountain Lion makes this as easy as possible by putting almost all of the settings in one place: the System Preferences window. In this lesson, we'll give an overview of the System Preferences window, and also show you how to create multiple accounts on your computer and adjust the Notifications settings.

To Open System Preferences:

  1. Click the Apple icon in the top-left corner of the screen and select System Preferences.

  2. The System Preferences window will open. You can then select the desired category to change settings.

You can also open System Preferences from the Dock or Launchpad.

Click the buttons in the interactive below to learn about some of the settings that you can change in System Preferences.

App Preferences

In addition to changing your computer's settings, you can change the settings for your apps. This allows you to customize the way your apps behave, and control the features that are important to you.
To access the settings for any app, open the app first. Then click the app name in the upper left corner of themenu bar, and choose Preferences from the menu.

Creating Additional Accounts

If multiple people are going to be using your computer, you'll need to decide whethereveryone will share an account, or whether each person will have their own account. Having a separate account for each person has some advantages. For example, each person will have their own desktop that they can personalize. In addition, parents will be able to set parental controls for each child's account.

Administrator, Standard, and Managed Accounts

Before you start making new user accounts, it's important to understand the different types:
  • Administrator: Administrator accounts are special accounts used for making changes to system settings or managing other people's accounts. They have full access to every setting on the computer. Every computer will have at least one Administrator account, and if you're the owner, you should already have a password to this account.
  • Standard: Standard accounts are the basic accounts you use for normal, everyday tasks. As a Standard user, you can do just about anything you would need to do, such as running software or personalizing your desktop.
  • Managed with Parental Controls: Managed accounts are the only type that can have parental controls. You can create a Managed account for each child, and then go to the Parental Controls settings in your System Preferences to set website restrictions, time limits, and more. You can also convert a Standard account into a Managed account by enabling parental controls.
Generally, it's safer to be logged in to a Standard account instead of an Administrator account. If you're logged in as an Administrator, it may actually make it easier for an unauthorized user to make changes to your computer. Therefore, you may want to create a Standard account for yourself, even if you're not sharing the computer with anyone. You'll still be able to make Administrator-level changes; you'll just need to provide your Administrator password when making the changes.

To Create a New Account:

  1. From your System Preferences, select Users & Groups.

    Changing Your Notifications Settings

    The Notification Center is a great feature for keeping you up-to-date. However, when you first begin working with OS X Mountain Lion, you might receive alerts and banners that you may not be interested in. You can modify the Notifications settings to select the apps you wish to receive alerts for and how you wish to be alerted.

    To Change Notifications Settings:

    1. Open the System Preferences window and click Notifications.

    2. The Notifications window will appear. In the In Notification Center pane, select the app you wish to modify.

    3. Select the alert style option you wish to apply to the app.
      • None: No alert will be displayed for the selected app.
      • Banner: When an alert is received for the selected app, a small banner will appear in the upper-right corner of the screen and will disappear automatically.
      • Alerts: When an alert is received for the selected app, a small window will appear on your screen and will remain on the screen until you close it.

    4. Select the alert settings options you wish to apply to the app.
      • Show in Notification Center: This setting will adjust how many alerts display in the Notification Center for the selected app. If you deselect the box, the Notification Center will not display alerts for that app.
      • Badge app icon: This setting displays a badge (a small number) on the selected app's Dock icon each time it has an alert. The badge indicates how many alerts have been received.
      • Play sound when receiving notifications: This option will play a sound when you've received an alert for the selected app. Deselect the box if you wish to turn off alert sounds.
